[1.98] Impossible to change a network from Sepolia using selector

[elena-zh]

Reported in https://cowservices.slack.com/archives/C0361CDG8GP/p1738585733181509

Connected to MM extension, each time when I try switching a network, I see 'base' indicator in the URL with no regard to a selected network, and the request to change a network is not sent to my wallet

Expected: the network should be changed

Additionally when a selected network is not present on user's Metamask, it should suggest the user to add it.

Seems to be something around this file:
https://github.com/cowprotocol/cowswap/blob/develop/libs/wallet/src/web3-react/utils/switchChain.ts#L45

Trying to activate a chain that is not present in Metamask insteda of suggest it to add window.ethereum.request()

Hi @re2005 , thank you for your suggestion.
It is already working this way on CoW Swap.

Thanks for the reply @elena-zh

Look at this screen video:

Usually if I select a network that is not present on my Metamask I should be prompted to add this network, and this is not what is happening.

@re2005 , thank you for clarification. Looks like the original issue is about this case you are describing. At least, on the video provided there you can see the same behavior.
